  • DISPERSANT, DISPERSED MATERIAL, RESIN COMPOSITION, MIXTURE SLURRY, ELECTRODE FILM, AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY
    Publication number: 20220204857
    Abstract: The present invention addresses the problem of providing: a dispersant which enables the production of a dispersed material having excellent dispersibility and storage stability even when the dispersant is used in a small amount; a dispersed material having excellent dispersibility and storage stability; an electrode film having excellent adhesiveness and electrical conductivity; and a non-aqueous electrolyte secondary battery having excellent rate properties and cycle properties. The problem can be solved by a dispersant which is a polymer containing 40 to 100% by mass of a (meth)acrylonitrile-derived unit and having a weight average molecular weight of 5,000 to 400,000.
